Corrosion Activity of Steel in Cementitious Controlled Low-Strength Materials vs. That in Soil


Controlled Low-Strength Materials (CLSM) are high performance fills produced and delivered by ready mix suppliers. CLSM places faster than conventional compacted fill, requires less jobsite equipment, increases jobsite safety, and minimizes future settlement problems. Consequently, the use of CLSM as backfill material is a very attractive option. However, there are numerous factors that influence soil corrosion on buried structures, such as the electrical resistivity of the backfill material along with its pH and drainage characteristics. Corrosion experiments in which steel coupons were placed in simulated soil or covered with cement-based CLSM then placed in simulated soil are discussed.
